Application:
The Sand Equivalent Test indicates the relative portion of undesirable clay-like or plastic fines and dusts that occur in granular soils and fine aggregates passing the No. 4 sieve. The sample to be tested is placed in a special solution of calcium chloride, formaldehyde and glycerin. After shaking the cylinder, it is allowed to stand for a 20-minute sedimentation period. Readings are then taken on the cylinder scale for the level of the top of the clay suspension and for the sand level. The "Sand Equivalent" is the sand reading divided by the clay reading x 100.
